Description

Anti-prying device for metal box cover

Technical Field

The utility model relates to a metal case lid, especially a pick-proof device for metal case lid for on the metal product.

Background

At present, the known mode that metal case lid and metal case block the side and combine is, one side of case lid is connected with the box with hinge or card hole, and the opposite side of case lid is fixed and is equipped with a lock core, and the inboard fixed latch hook that is equipped with of lock core, the box then has set up a boss or the card hole that can block the latch hook in the below that is close to the case lid lock core, and the operating portion step is: the cover is covered, the key is inserted into the lock cylinder hole, the key is rotated to drive the lock hook to be clamped into the boss or the clamp hole on the box body, the cover is locked on the box body, but the cover is not firmly locked on the box body by the method, because the boss or the clamp hole is only hung by the lock hook, the cover is not tightly pressed on the box body, the cover is still loose on the box body, a gap is reserved between the cover and the box body, a thief inserts a flat screwdriver into the gap between the cover and the box body to pry, the lock core, the lock hook, the boss or the clamp hole are easily deformed by prying, particularly the lock hook is easily deformed, the thief can easily open the cover, for example, a remote control parking stall lock installed in a car parking lot is frequently used for stealing a storage battery by prying the cover due to the defects of the prior art of the cover, a coin-inserting shopping box, a power supply equipment box and the like are installed in a public place and do not, the potential safety hazard that the box cover is easy to pry open exists, so people need a device for preventing the metal box cover from being pried to firmly and stably lock the box cover on the box body and prevent a thief from opening the box cover by using damaging means such as prying and smashing.

Disclosure of Invention

The utility model aims to achieve the aims by the following measures, which mainly comprises a key (1), a lock core shaft (2), a lock body (3), a lock body positioning frame (4), a screw thread (5), a threaded hole (6), a box cover (7), a box cover fixing plate (8), a screw (9), a box body threaded hole (10) and a box body (11), wherein the box cover (7) is provided with the lock body positioning frame (4), the inside of the lock body positioning frame (4) is of a diagonal shape, a polygonal shape or a non-circular shape, the appearance of the lock body (3) is of the diagonal shape, the polygonal shape or the non-circular shape, the lock body (3) can not rotate in the lock body positioning frame (4), the bottom of the lock body positioning frame (4) is provided with the threaded hole (6), the lower end of the lock core shaft (2) is provided with the screw thread (5), one side below the box cover fixing plate (8) is arranged on one, lock body (3) are equipped with round pin or boss (16), lock body locating rack (4) are equipped with round pin or boss (16), and lock body (3) are equipped with spout (15), the lower extreme of lock core axle (2) is equipped with bayonet lock (18), and lock body locating rack (4) are equipped with breach (17) and through-hole (19).

The utility model has the advantages that: the principle of locking the existing metal box cover is completely changed, an original locking structure is divided into two parts, namely a locking head part and a pressing part, the locking head part is only responsible for plugging and opening a channel on the box cover, a screw of the pressing part is responsible for screwing a box fixing plate on a box nut, the hooking force of a locking hook is replaced by the screwing force and the firmness of the screw, a thief wants to pry the screw from the nut almost impossible, namely, the loosening of the box cover is eliminated, the gap between the box cover and the box body is removed, and a hard device such as a flat screwdriver is extremely difficult to take down, so that the anti-prying performance of the box cover is greatly improved, the insecure defect that the lock cylinder of the original box cover directly drives the locking hook to hook a boss or a clamping hole of the box body is eliminated, the contact strength and the rigidity of the box cover and the box body are improved, the anti-prying purpose is achieved, and meanwhile, the great difficulty is increased for the thief to unlock by using a technical, because originally the thief unblanks with technical means as long as rotatory 90 degrees with the lock core, this case lid is stolen promptly, however this pick-proof device need with 360 degrees rotatory 4~8 circles of lock cores, so the technical degree of difficulty of opening is extremely big, after taking out the lock body, still need to use the allen key to move back the screw soon, just can steal the case lid, another benefit of the utility model is that the lock head body is not fixed mounting on the metal casing lid, can change at any time to prevent the stolen or risk of being prepared of key, this pick-proof device specially adapted remote control parking stall lock of automobile parking area installation, because the case lid of remote control parking stall lock need not often be opened, only the battery has used three ~ five months to need charge, just opens once. So this pick-proof device specially adapted remote control parking stall lock, sharing ground lock, electric motor car charging case, coin-feed shopping case, communication or power supply unit case etc. install in the product that does not need often to open in public place, if do not establish pick-proof device because this kind of metal case lid, the case is stolen to take place easily, the utility model discloses a another benefit is that the locking head body is not fixed mounting on the metal case lid, can change at any time as required, for example the staff who is on duty who just pins the case lid with the locking head part that has carried certainly to prevent that other people from stealing the key or leaving staff steal the risk that the key brought and so on.
